To all whom it may cone-c2 77.:

Be it known-that- I, SIDNEY M. ISRAEL,

a citizen of the United States, and a resident of lVoodhaven, county ofQueens, city and State of New York, have invented certai r new anduseful Improvements in Adjustable Supports for Electric Lights, otwhichthe following is a specification suliicient to enable those skilled inthe art to which the invent-ion appertains to utilize the same.

My imlprovements relate to the class of electric light fixturesdesignated in Letters Patent No. 1,475,768, issued to me Nov. 21, 1923,such fixture-s being utilized more particularly for the support ofelectric 'lamp bulbs intended tosimulate the use of candles in a mannernow well known in the art, my present invention being designed -toadaptthe type of fixture describedand claimed in said Letters Patent moreeffectually to the exigencies and requirements of actual use, andconsisting in'fthe "specific construction, combination' and arrangementof parts described and claimedherein whereby such adaptability isattained, and the fix' ture rendered more positive in character, all ashereinafter fullyset forth. y

In. the accompanying drawings I exemplify a practical embodiment of theessential features of'mfy invention in ,airadjustable lamp supportconsisting of acne-piece basic section and a one-piece extensionsection, each of said sections being made from a blank of sheet metaldie formed and bent into the requisite shapes, with interlocking partsas related to each other. although I do not limit myself to theidentical configuration of parts thereof shown, since modifications in Iminor details and mechanical expedients may be, resorted to with likeresult, and without departing from the spirit and intent ofmy lampsocket provided with two securing screws; y

v Fig. 15, is an enlarged view of the lower ly illustrate theinterlocking of the conjunctive edges of the tubular socket of said base'ineinber;

Figs! 16 and 17. are views similar to Fig.

' socket arms such as shown in Figs. 3 and 4'. The'lower b21810.orzsocket member B, of-

my improved extensible lamp support is formed from a single blank ofsheet metal,

stamped out substantially as shown in Figs.

7and 14, and is then bent into tubular form as shown more particularlyin Fig. 19, ofthe drawings. Said blank is formed with portion of saidbasic member, to more clear- 15, showing modifications in the formation,of the lnterlocking edges of said tubular portion ,of the basic member;

tongues b, 7),- which are inturned for the pur pose of maintaining thealignment of the ad ustable upper member A, of the device.

The lower part of the blank B, is formed with lateral extensions Z), 6,which are inturned to form the cylindrical socket 12 which is internallyscrew threaded as shown more particularly in Fig. 6, for attachment tothe usual tubular wire conduit, not shown. In order to stiffen andreinforce this threaded cylindrical socket IF, it is formed with anannular head I); and in order to prevent any possibility of theseparating apart of the abutting edges of the cylindrical socket 5 Iprefer to form the latter with inter locking parts, substantially asindicated in Figs. 13, 14:, 15, 16 and 17 of the drawings, in which Z),represents a coupling tongue, and 6 a correspondingly shaped recess forthe reception of, and engagement with, said tongue 6 Thus the perfectcylindrical shape of the screw socket I), is assured against lateralstrain upon the socket member B, and reinforced against the action ofthe binding screw b, which latter is provided forthe purpose ofpreventing the turning of said socket member B, on its centrallongitudinal axis after attachment to the aforesaid electric wireconduit. The upper part of the basic member B, is also provided with aset and binding screw 6 by means of which the upper or lamp socketsection A, of the device is adjustably held in position on the basicsection B, as shown more particularly in Fig. 6, of the drawings, saidset screw Z2 acting in conjunction with the inturned lugs Z), Z), inthis respect.

The adjustive upper section A, of the device, to which the lamp socketS, is attached in use, is also formed from a single blank of sheet metalsuch as shown in Figs. 9 and 11, of the drawings, the only difference inthe two shapes of blanks shown being that the bracket extensions a, a,are longer in that shown in Fig. 9, for the purpose of utilization as ameans of securing the lamp socket S, between them by means of a singlecouplingscrew 70, as indicated in Figs. 1, 2

socket supporting arms a, a, the device is adapted to the support oflamp sockets of various manufacture.

. The blank A, is also formed with lateral lugs 66., a, adjacent to theextensions a, a, which lugs a, a, are inturned and beaded to reinforcesaid lamp socket supporting arms a, a, as shown more particularly inFig. 6, of the drawings, which figure also illustrates the function ofthe inturned lugs a (L in acting as stops in conjunction with the inturned tongues 6, Z), of the basic member B, to prevent the separationof the two members A, B, of the device.

What I claim as my invention and desire to secure by Letters Patent, is

As an article of manufacture, an adjustable support for electric lampsofthe char acter designated, comprising a basic member consisting of asingle. piece of sheet metal bent into tubular shape and formed with aninternally threaded and annularly beaded socket at its lower extremity,and with inturned retaining lugs at its upper extremity, a set screwpositioned to act in conjunction with said internally threaded socket,an adjustable member consisting of a single pieceof sheet metal, saidadjustable member being mounted upon said basic member and formed withextension arms for attachment to a lamp socket, and also being formedwith inturned stop lugs and an adjustable set screw mounted on the upperportion of the basic member and bearing against said adjustable member,substantially in the manner and for the purpose set forth.
